Range Syntax

Simple ranges:

node1000..1099 == node1000..99 # auto pads digits to the end of the range

1..100 # numeric only ranges

foo1-2.domain.com == foo1.domain.com-foo2.domain.com # domain support

209.131.40.1-209.131.40.255 == 209.131.40.1-255 # IP ranges

Clusters:

A cluster is a way to store node membership into groups. Depending on your backend module how this is stored may vary. In the case of the YAML module, a cluster is defined by the membership of the CLUSTER key
